The operation of the hair dryer configured as described above will be described below. First, by pressing the operating portion 74 with a finger, the operation changeover switch 89 is switched to g, h, i in order. Along with that, hot air is generated, cold air is generated, and operation stops. Only when hot air is generated, the temperature controller 86 can energize the heater 80, and when hot or cold air is generated, the air volume controller 87 operates so that the motor 84 turns. The output signal of the temperature detector 78 is input to the temperature controller 86 via the signal conversion circuit 85. The temperature controller 86 energizes the heater 80 so that the temperature set by the temperature changeover switch 90 is reached. Heater 8

[0007]

However, in the above-mentioned conventional structure, since the motor is provided with a brush, the rotating noise is large and the life is short. Also, since the heater and the air blower are integrated, they are brought near your ears when you use them, so there is the problem that the noise generated by the motor and fan is very annoying, and at the same time it is heavy and large. There is also a problem that the hands and arms are easily tired when they are frequently used because they are difficult to handle.

Further, since a large amount of air vortex is generated by the heater, there is a problem that an offensive sound is generated.

Further, since it is easy to adjust the direction of the blowing portion and the distance to the hair in a barber shop, the tubular portion of the housing outside the heater portion may be grasped and used. At that time,
There is a problem that it is difficult to operate because it causes an imbalance when the grip portion holds it.

(Eleventh Invention)

[0021]

In the first means, when a hair dryer is used, it is sufficient to hold only the tip of the air guide tube without having a motor and a fan, so that the portion to be held by hand can be made light and small.
This improves operability and reduces hand and arm fatigue. Further, since it is not necessary to have a motor and a fan, the size can be increased, and it is possible to obtain an air volume higher than the conventional one at a low rotational speed, so that noise such as wind noise around the fan can be reduced.

The above-mentioned second means can be used in a state where both hands are separated because the air guide tube can be bent and can hold the bent shape. Therefore, the hair can be brushed up with both hands and the warm air can be efficiently applied to the hair or scalp to dry quickly. In addition, the quick drying reduces the usage time, and since it is unnecessary to have anything, hands and arms do not easily get tired.

In the third means, since the heating surface of the heater is wide and continuous, it is not necessary to arrange the heaters in multiple stages and air vortices such as Karman vortices can be suppressed. Therefore, the air resistance is reduced, the load on the air blower is reduced, the efficiency of air blow is improved, and the noise due to the air vortex is also reduced.

In the fourth means, since the heater is provided in the housing, only the blow-out portion of the air guide tube is held by hand when used, which is light and easy to handle.

In the fifth means, a heater is provided at the blow-out portion of the air guide tube, so that a wide range of materials such as vinyl chloride, which produces an offensive odor from around 70 ° C. to 80 ° C., can be applied to the air guide tube. , The heat loss can be made very small.

In the sixth means, the heater in the housing warms the air to some extent and heats it again by the heater in the blowing portion of the air guide tube. As a result, a wide range of materials such as vinyl chloride that emits an offensive odor from around 70 ° C to 80 ° C can be applied to the air guide tube. Therefore, it becomes easy to reduce the price, reduce the weight, and improve the operability and durability. Also, since the heater of the blow-out part can be made smaller and lighter, the blow-out part of the air guide tube, which is the part to be held by hand, can be made lighter while suppressing heat loss, and it is easy to handle without hand or arm fatigue. In addition, the noise generated around the heater becomes smaller. Then, the sound generated around the heater in the housing is attenuated while being transmitted through the air guide tube, and the noise level emitted outside becomes low.

The seventh means is an output of a switch for detecting that a person has it, and can stop the power supply to the heater and the motor. As a result, when the hair dryer is left with the power on, wasteful power is prevented from being consumed and the hot air that blows out does not heat anything near the hair dryer, thus preventing the risk of burns or ignition. It will be possible.

In the eighth means, the brushless motor is used as the motor to eliminate the brush noise, and the noise can be reduced.

In the ninth means, since the blowing portion housing which is a portion to be held by a hand has a cylindrical shape, when the portion is moved, the weight is unbalanced in the related art, which is one of the difficulty in handling. It becomes easier to adjust the direction of the balloon and the distance to the hair. This makes it easy to handle, suitable for the forms currently used in barber shops. At the same time, since the outlet of the outlet housing is close to the hand held, it is easy to estimate the position of the outlet, and it is possible to prevent the outlet from being too close to the hair and damaging the hair.

In the tenth means, the band is supported by the palm and the back of the hand without holding the blowing portion housing only by gripping force, so that the fatigue of the hand can be reduced and the maneuvering can be performed quickly, which is very convenient. Get better
Further, since the fingers of the hand supporting the blowing portion housing can be moved, when a temperature setting switch or the like is provided on the blowing portion housing with the thumb, forefinger, middle finger, etc., these can be easily operated while operating. Is possible. Therefore, the hand can be quickly handled without getting tired, and the temperature setting switch provided on the blower housing can be easily operated while working.

The eleventh means is a switch or a variable resistor on the blow-out housing, which can immediately adjust the air flow rate and the temperature without having to replace the switch. As a result, the operability is greatly improved.

Is a sheet heating element.

The operation of the hair dryer configured as above will be described. First, the air is dehumidified by the brushless fan motor 6 including the brushless motor 28 and the fan 27 provided in the air blower housing 24.
After being dehumidified by, it is carried by the heater 5 (25) to the blow-out housing 1 (18) from the air guide tube 2 (23) that can maintain the bent shape. The air further heated by the heater 4 (19) is exhausted from the outlet. The temperature detector 3 (22) near the air outlet detects the temperature of the warm air and inputs it to the comparator 9 via the signal conversion circuit 7. Variable resistor 1 by temperature setting knob 14 (30)
3 is set, and the variable reference voltage generation circuit 1 proportional to this is set.
The output signal of 1 is input to the comparator 9 through the contact a of the operation mode changeover switch 17 (29). The temperature set value and the detected temperature are compared by the comparator 9, and the temperature controller 8 is instructed,
By this command, the energization of the heater 4 (19) of the blowing part and the heater 5 (25) of the blower part is controlled so as to reach a predetermined temperature. On the other hand, the air volume set by the variable resistor 15 by the air volume setting knob 16 (31) is input from the variable reference voltage generating circuit 12 to the air volume controller 10 through the operation mode changeover switch 17 (29). The air volume controller 10 controls the brushless motor 28 of the brushless fan motor 6 so that the air volume becomes a predetermined air volume.

The operation changeover switch 17 (29) is switched to a stopped state when the conduction circuit is the contact c, a blast only operation when the contact b is present, and a warm air operation when the contact a is present. The wind noise can be reduced by arranging the heater 4 (19) or the heater 5 (25) such that the heating surface is along the traveling direction of air like the planar heating element 33 attached to the support plate 32. . When the warm air becomes extremely hot, the thermostat 21 shuts off the power supply to the heater 4 (19) or the heater 5 (25). Further heater 5
When (25) heats up abnormally, the energization of the heater 5 (25) is immediately cut off by melting the thermal fuse 20.

As described above, according to the present embodiment, since the air blower may be left stationary and handled only by the air blower housing of the air guide tube, the weight supported by the hand is greatly reduced. Further, since the air guide tube maintains the bent shape, it is possible to use the air guide tube by releasing the hand from the blowout portion housing. Therefore, the hands and arms do not get tired and the hair can be dried quickly by using the hair with both hands. Also, since the heater is provided in the air blower and blower housings, a wide range of materials such as vinyl chloride, which emits an offensive odor from around 70 ° C to 80 ° C, can be applied to the air guide tube, resulting in low cost and light weight. It becomes easy to improve operability and durability. Also, since the heater of the blow-out part can be made smaller and lighter, the blow-out part of the air guide tube, which is the part to be held by hand, can be made lighter while suppressing heat loss, and it is easy to handle without hand or arm fatigue. In addition, the noise generated around the heater becomes smaller.
Then, the sound generated around the heater in the housing is attenuated while being transmitted through the air guide tube, and the noise level emitted to the outside is lowered. Further, since the portion to be held by hand becomes a cylindrical blow-out portion housing and there is no protruding portion such as a grip portion, it can be handled without feeling an imbalance in weight. At the same time, since the outlet of the outlet housing is close to the hand held, it is easy to estimate the position of the outlet, and it is possible to prevent the outlet from being too close to the hair and damaging the hair. In addition, the brushless motor eliminates the brush noise, and because the air blower is separated from the air blower to be installed, the noise around the fan is kept away, and the fan becomes larger and the motor rotates at a lower speed to reduce the fan noise. The wind noise due to the heater is reduced by reducing the wind noise and making the heater planar. Since the heater using the planar heating element has a wide and continuous heating surface, it is not necessary to arrange the heaters in a plurality of stages and air vortices such as Karman vortices can be reduced. Therefore, the air resistance is reduced, the load on the air blower is reduced, the efficiency of air blow is improved, and the noise due to the air vortex is also reduced. Also,
Dehumidifying the air blown by the dehumidifying agent improves the drying ability. In particular, when used in a place with high humidity such as a bathroom washbasin, it is possible to shorten the time of applying heat stress to hair.

The heater 5 (25) in the housing may be omitted and only the heater 4 (19) may be used. in this case,
It is possible to reduce the weight of the blow-out portion of the air guide tube, which makes it easier to operate when manually changing the position of the blow-out portion of the air guide tube, and requires less force to support the air guide tube.

The heater 4 (19) in the housing may be omitted, and only the heater 5 (25) may be used. in this case,
Since heat is not applied to the air guide tube, a material weak to heat can be applied and the heat loss can be very small.

To be done. The blowing housing 34 (56) has a band 55 (71) for inserting a hand holding this portion. When the hand is inserted, the holding switch 45 is activated and the stop switch 44 is interlocked with the heater 37 (57) and the heater 38 ( 66) and conduction to the brushless fan motor 39. Also,
When the hot air becomes extremely hot, the thermostat 60 shuts off the power supply to the heater 37 (57) or the heater 38 (66). Further, when the heater 37 (57) abnormally generates heat, the thermal fuse 59 is blown to immediately cut off the energization of the heater 37 (57). Also, the power switch 7
0 turns on / off the power supply of the entire device.

As described above, according to the present embodiment, the air blower can be left stationary and handled only by the blower outlet housing of the air guide tube, so that the weight supported by the hand can be greatly reduced. Therefore, the hands and arms do not get tired and it is a great work improvement when frequently used in a barber shop. In addition, since the heater is provided in the blower unit and the blower unit housing,
