Description

[Detailed description of the invention] [Industrial application field] This invention relates to a hair dryer used for drying and styling hair.

[Conventional technology]

Conventionally, hair dryers have a handle 71 provided at the rear end of a cylindrical housing 70, as shown in FIG. 12, or a handle 71 provided at the rear end of the housing 70, as shown in FIG. There is one with 71.

FIG. 13 shows a specific structure of the example shown in FIG. 12.
A motor 76 with a fan 75 attached thereto and a heater 77 are housed in a cylindrical housing 70, and the handle 7
A power cord 73 extending from 1 is connected to a motor 76 and a heater 77 by a lead wire 78.
The lead wire 78 is inserted into the notch 74 provided in the housing 70.
It is introduced into the housing 70 from. Handle 7
1 is designed to be foldable around a support shaft 79.

[The problem that the idea aims to solve]

In the two formats shown in Figures 12 and 14,
In terms of ease of use, it is better to have the handle 71 closer to the center in FIG. 14.

In the case where the handle 71 is provided near the center, it is necessary to form a large notch 74 for passing the lead wire 78 from the handle 71 to the housing 70 as shown in FIG. That is, the depth Y of the notch 74
becomes deeper.

However, if the notch 74 is formed deeply, the strength of the housing 70 will be weakened, and there is a problem that both sides of the notch 74 will open in the direction of arrow a.

The reason why the lead wire insertion opening is formed as a notch 74 is that if a hole were used instead of the notch 74, the mold for manufacturing the housing 70 would have a complicated configuration.

The purpose of this invention is to provide a hair dryer in which the housing does not open on both sides of the notch even if the notch provided in the housing for inserting a lead wire is formed deeply.

[Means to solve the problem]

The hair dryer of this invention has a cylindrical housing with a notch through which lead wires for the motor and heater pass from the handle to the housing, and a suction port member is fitted into the housing.
Engaging portions and engaged portions that engage with each other in the circumferential direction are provided at both circumferential positions of the notch of the housing and the suction port member, respectively.

[Effect]

According to the configuration of this invention, the engaged portions of the suction port member fitted into the housing engage in the circumferential direction with the engaging portions on both sides of the notch of the housing, so that no external force acts to open the notch. However, the external force is received by the suction port member.

〔Example〕

An embodiment of this invention will be explained based on FIGS. 1 to 11. FIG. 2 is an exploded perspective view of the entire device. The main body of this hair dryer is constructed so that all parts except a nozzle 2 are assembled into a cylindrical housing 1 in the direction of arrow Q. That is, the discharge port grid 3 is inserted into the housing 1 from the rear end, which is the suction side end, and then the heater 4, the ventilation block 5, the suction port housing 6, and the suction net 7 are inserted.
are sequentially inserted into the housing 1 and assembled. The nozzle 2 fits into the front end of the housing 1. Heater 4
In this example, a resistance heating wire 4a is wound around a cross-shaped heater substrate 4b, and this is housed in a heater surrounding frame 4c. The blower block 5 is constructed by assembling a motor 10 with a fan 9 attached to its output shaft on a ring-shaped fixed frame 11. The suction port housing 6 and the suction net 7 constitute a suction port member 8.

The discharge port lattice 3 is formed by forming a vertical lattice 3b on a ring-shaped frame 3a, and has positioning notches 3c at two locations on the outer periphery. The discharge port grid 3 is positioned by engaging the positioning notch 3c with the positioning protrusion 12 on the inner surface of the housing 1. The heater 4 to be installed next is a vertical heater board 4b.
is positioned between the vertical grids 3b of the discharge port grid 3. Fixed frame 1 of ventilation block 5
1 is rotatably inserted into the housing 1 and positioned in the suction port housing 6 as described later.

The suction port housing 6 is entirely fitted into the rear end of the housing 1 to prevent each part inside the housing 1 from coming off. The suction port housing 6 is the housing 1
It has a handle attachment piece 14 that overlaps the handle attachment piece 13 near the rear end, and these handle attachment pieces 1
Screw 16A for attaching the handle inserted into 3 and 14
is fixed to the housing 1 by. Suction net 7
The peripheral wall portion fits into the fitting gap between the outer circumferential surface of the suction port housing 6 and the inner circumferential surface of the housing 1,
It is attached to the suction port housing 6 by engaging the net engagement protrusion 27 with the net engagement groove 28 of the suction port housing 6.

The handle 15 is a pair of split handles 15A, 1
Consisting of 5B, 18 switches, 19 switch buttons,
Switching operation plate 20 and cord bushing 2
1 and are connected to each other by screws 16A and 16B. At this time, one end of the handle 15 is rotatably attached by sandwiching the handle attachment pieces 13, 14 of the housing 1 and the suction port housing 6 together with the rotary ring 17, and inserting the screws 16A into the attachment pieces 13, 14. power cord 22
is the cord bushing 21 at the other end of the handle 15.
Extends from.

The positioning structure of the ventilation block 5 and the suction port housing 6 will be explained. As shown in FIG. 11, the fixed frame 11 of the blower block 5
The guide protrusion 23 has a positioning recess 24 into which a protruding guide piece 23 is inserted, and the guide protrusion 23 has tapered portions 23a on both sides of its tip. Fixed frame 11 is housing 1
Since the suction port housing 6 is rotatably inserted into the housing 1, even if the rotation angle is slightly deviated, the tapered portion 23a of the guide protrusion 23 engages with the side edge of the positioning recess 24, thereby inserting the suction port housing 6 into the housing 1. As the suction port housing 6 is completely inserted, the fixed frame 11 rotates and is positioned at a predetermined angle.

As shown in FIG. 3, a power cord 22 extending from the handle 15 and a heater 4 inside the housing 1
And it is connected to the motor 10 by a lead wire 29.
This lead wire 29 is inserted into a notch 26 (see FIG. 10) provided at the rear end of the housing 1. Notch 2
As shown in FIG. 1, a notch fitting portion 6a in the peripheral wall of the suction port housing 6 fits into the opening portion 6. As shown in FIG.

A pair of engaging portions 30 consisting of groove-shaped recesses are provided on both sides of the notch 26 of the housing 1, and an engaged portion 3 consisting of a protrusion that engages with the engaging portions 30.
1 is provided protruding from the outer surface of the peripheral wall of the suction net 7. FIG. 4 shows the engaged state, and FIG. 5 shows an enlarged cross section of the engaged portion.

According to the hair dryer having this configuration, the engaged portions 31 of the suction net 7 of the suction port member 8 fitted into the housing 1 are attached to the engaging portions 30 on both sides of the notch 26 provided in the housing 1 for inserting the lead wire. Since they engage in the circumferential direction, even if an external force is applied to open the notch 26, this external force is received by the suction net 7. Therefore, the housing 1 has notches 2 in terms of strength.
It is the same as the cylinder without 6. Therefore, the notch 26
Even if the notch 26 is formed deeply, the housing 1 is prevented from opening on both sides of the notch 26. Therefore, the handle 15 can be arranged closer to the center than the rear end of the housing 1 to improve usability.

Further, a discharge port grid 3 is provided in the cylindrical housing 1.
Since the heater 4, the blower block 5, and the suction port housing 6 are all inserted and assembled in the same direction, assembly and disassembly are easy, and maintenance can be easily performed. As mentioned above, the positioning protrusions 12 of the housing 1 (FIG. 2), the engagement of the vertical grid 3b of the discharge port grid 3 with the heater board 4b, and the guide protrusions 23 of the suction port housing 6 (FIG. 11) ) etc., the parts can be reliably positioned simply by inserting them, making assembly even easier.
Since the suction port housing 6 is fixed to the housing 1 with screws together with the split handles 15A and 15B, disassembly and assembly are easy.

Furthermore, the suction port housing 6, which prevents each component stored in the housing 1 from coming off, is entirely housed within the housing 1, and the joint between the housing 1 and the suction port housing 6 is located in the notch 26 of the housing 1. It only occurs in parts. Moreover, this notch 26 is a mounting portion for the handle 15, and is a difficult-to-see location. Therefore, the joint between the housing 1 and the suction port housing 6 is not noticeable, and the appearance is good.

The appearance will be compared with the conventional example shown in FIG. In the example shown in FIG. 13, a heater 77 and a motor 76 are housed in the housing 70 in the same direction to facilitate disassembly and assembly, and a rear housing 80 prevents these components from coming off. The rear housing 80 is connected to the rear side of the housing 70 and has a hook 8.
2 is engaged with the engagement recess of the housing 1. Since the housing 70 and the rear housing 80 are joined back to front in this way, the seam 81 is formed around the entire circumference and stands out, spoiling the appearance. Furthermore, if the hooks 82 are not fully engaged during assembly, a step will occur at the seam 81, further deteriorating the appearance.

On the other hand, in this embodiment, the joints are made less noticeable and the appearance is improved while maintaining the ease of assembly and disassembly.

In the embodiment described above, the suction port housing 6 and the suction port net 7 were formed separately, but they are integrated to form the suction port member 8, and an engaged portion for preventing the notch 26 from opening is provided in the suction port member 8. 31 may be provided. Further, the engaging portion 30 may be a convex portion, and the engaged portion 31 may be a concave portion. Furthermore, although the handle 15 is foldable in the above embodiment, the handle 15 may be fixed.

[Effect of idea]

According to the configuration of this invention, the engaged portions of the suction port member fitted into the housing engage in the circumferential direction with the engaging portions on both sides of the notch for inserting the lead wire provided in the housing, so that the notch is opened. Even if such an external force is applied, the external force is received by the suction port member, and the housing has the same strength as a cylindrical body without a notch. Therefore, even if the notch is formed deeply, the housing is prevented from opening on both sides of the notch.
