Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a hair dryer having axial flow blades.

[Technical background of the invention]

BACKGROUND ART Hair dryers have conventionally been provided that are capable of curling hair by attaching an accessory to the exhaust port side of a main body case that generates hot air, for example. This device has an air outlet at one end of the cylindrical main body case that also serves as a grip, and the aforementioned air outlet at the other end, and an air outlet for connecting to a power cord approximately in the center of the air intake port. A cylindrical power receiving terminal holder equipped with a power receiving terminal holder is provided at a position, and a heater and a motor are sequentially provided inside the main body case from the exhaust port side, and an axial flow vane rotationally driven by the motor is installed in the main body case. It was configured so that it faced the intake port.

[Problems with background technology]

However, in the above-mentioned conventional type, the heater and motor are located inside the main body case in the flow path of the air generated by the axial flow blades rotationally driven by the motor, and the motor is particularly located in the center of the main body case. Because of this, the air passes between the outer circumferential surface of the motor and the inner circumferential surface of the main body case, but in this case, if the gap is narrow, sufficient air cannot be blown because the static pressure of the axial flow vanes is inherently low. Therefore, if the interval is made large, there will be a problem that the main body case will become larger as a whole, and even if the interval is made this way, a part of the air due to the axial flow blades will not flow toward the outer peripheral surface of the motor, and the shaft of the motor will become larger. There was also the problem that noise was generated when the blade hit the surface on the flow blade side.

[Purpose of invention]

The present invention was developed in view of the above circumstances, and its purpose is to obtain high static pressure while using axial flow vanes, and to obtain sufficient air volume without enlarging the main body case. , to provide a hair dryer that can reduce noise.

[Summary of the idea]

The present invention provides a power receiving terminal holder provided approximately at the center of the intake port of the main body case with a generally conical air guide section that expands toward the axial flow blade side, thereby increasing static pressure and increasing the axial flow. It is characterized in that the wind generated by the flow blades can be guided between the outer peripheral surface of the motor and the inner peripheral surface of the main body case.

[Example of idea]

An embodiment of the present invention will be described below with reference to the drawings. First, in FIG. 1, reference numeral 1 denotes a substantially cylindrical main body case, which has an intake port 2 around an end surface 1a at one end and an exhaust port 3 at the other end. Inside the main body case 1, a heater 4 is disposed on the side of the exhaust port 3, and a motor 5 is disposed approximately in the center, and the rotating shaft 5a of the motor 5 is oriented toward the side of the intake port 2. An axial flow vane 6 is attached to the tip thereof so as to face the intake port 2. Reference numeral 7 denotes a housing of the motor 5, which includes guiding blades 8 located between the outer circumferential surface of the motor 5 and the inner circumferential surface of the main body case 1.
is integrally molded. Reference numeral 9 denotes a cylindrical power receiving terminal holder made of an electrical insulator such as plastic, and one end thereof is attached to a mounting hole 10 formed approximately in the center of the end surface 1a of the main body case 1, so that this power receiving terminal The holder 9 is located approximately at the center of the intake port 2 portion. Reference numeral 11 denotes a wind guiding portion, which is integrally formed with the power receiving terminal holder 9 so as to form a substantially conical shape that widens from the other end toward the axial flow blade 6 side. Reference numerals 12 and 13 denote power receiving terminals, which are located within the power receiving terminal holder 9 and attached thereto, and these power receiving terminals 12 and 13 have lead-out plate portions 12a and 13a. The portions 12a and 13a are led out to the air guiding portion 11 and attached to the inner surface thereof. 14 and 15 are lead wires extending from the lead-out plate portions 12a and 13a of the power receiving terminals 12 and 13 to the heater 4 and the motor 5, and 16 is an end plate provided in the power receiving terminal holder 9. On the other hand, 1
7 is a power cord wire, and there is a plug 18 at the tip of the power cord wire.
The plug 18 has a well-known configuration in which a power supply terminal 19 is provided at the tip and a power supply terminal 20 is provided on the peripheral surface of the base end side of the power supply terminal 19. By inserting the plug 18 of the power cord wire 17 into the power receiving terminal holder 9, the power feeding terminal 19 and the power receiving terminal 12 can be connected to the power feeding terminal 20.
and the power receiving terminal 13 are electrically connected to each other.

Now, in the above configuration, when the plug 18 of the power cord wire 17 is inserted into the power receiving terminal holder 9 and the power switch (not shown) is turned on, the heater 4 generates heat and the motor 5 is driven to drive the shaft. The flow blade 6 is rotated. Air is sucked into the main body case 1 from the intake port 2 by the rotation of the axial flow vane 6, and this sucked air flows through the axial flow vane along the outer circumferential surface of the air guide section 11 as shown by the arrow in FIG. 6
The air is guided near the outer diameter end of the motor 5, passes between the outer peripheral surface of the motor 5 and the inner peripheral surface of the main body case, is heated by the heater 4, and is discharged to the outside from the exhaust port 3. Therefore, at this time, almost no air flow, ie, wind, is generated near the center of the axial flow blade 6, and the wind only passes near the outer diameter end of the axial flow blade 6.

According to this embodiment, since the substantially conical air guiding portion 11 is provided on the intake port 2 side of the axial flow vane 6, even though the axial flow vane 6 is used, the diagonal flow, which is said to have a high static pressure, can be carried out. It is possible to obtain the same air blowing effect as a blade, increasing the static pressure for air blowing, and therefore, even when the space between the outer circumferential surface of the motor 5 and the inner circumferential surface of the main body case 1 is narrow, sufficient air volume can be obtained. can. Therefore, there is no need to increase the size of the main body case 1. In addition, since the air is guided to the inner circumferential surface side of the main body case 1 by the air guide section 11, the wind generated by the axial flow blades 6 does not hit the surface of the motor 5 on the axial flow blade 6 side. Noise generation can be significantly reduced. Furthermore,
Since the wind guide part 11 is provided in the power receiving terminal holder 9 located approximately at the center of the intake port 2, the wind guide part 1
The position No. 1 is the optimum position for the axial flow blade 6, and the static pressure characteristics can be increased. Moreover, the power receiving terminal holder 9 can be used for installing the wind guide section 11, and the complexity of the structure can be suppressed. .

In particular, in this embodiment, the wind guiding portion 11 is integrally molded with the power receiving terminal holder 9, so that the structure can be further simplified. However, the wind guiding portion 11 does not have to be integrally formed on the power receiving terminal holder 9, but may be provided as a separate member on the power receiving terminal holder 9, if necessary. In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but may be implemented with appropriate modifications within the scope of the gist.

As is clear from the above description, the present invention has a heater and a motor inside a main body case that has an inlet and an outlet, and a power receiving terminal holder located approximately in the center of the inlet. A hair dryer in which an axial flow blade is provided and is provided to face the intake port and is rotationally driven by the motor,
The power receiving terminal holder is characterized by being provided with a generally conical air guiding portion that expands toward the axial flow blade, and thereby, high static pressure can be achieved even though the axial flow blade is used. This makes it possible to obtain sufficient air volume without increasing the size of the main body case, and also to reduce noise.Furthermore, the existing power receiving terminal holder can be used to install the wind guide part, which reduces the complexity of the structure. It has excellent effects such as being able to suppress
