Description

[Detailed description of the invention] [Industrial application field] This invention relates to a hair dryer equipped with a brush at the outlet, and is particularly applicable to hair dryers in which the brush base that supports the brittle is formed of a resilient material such as rubber. shall be.

[Prior Art] In this type of hair dryer, the brush 15 is composed of a brittle 22 and a brush base 21 that supports it, as shown in FIG.
is attached to the air outlet 6 of the dryer body 1,
The present applicant has previously proposed a device in which the blitzles 22 spread out in a radial shape suitable for hair blowing work (Utility Model Application No. 174642/1983). In such a hair dryer, in order to maintain the shape of the brush base 21 during use, the inside of the brush base 21 is supported by a brush support 16.

[Problem that the invention attempts to solve]

This invention enables the brush base 21 to be securely fixed in the case where the brush base 21 is formed of a resilient material such as rubber as described above.
The brush base 21 may shift during use, or the mounting frame 4
This is intended to solve problems such as a gap being created between the brush window 14a and the brush window 14a, which impairs the appearance.

This kind of problem occurs because the mounting frame 14 is a plastic molded product with high molding precision, whereas the brush base 21 is a molded product of rubber or the like that tends to have large dimensional variations. In addition, deformation or misalignment of the brush base 21 can occur in the brush window 14a, as illustrated in FIG. 6 of the present embodiment.
This is particularly likely to occur at locations where the brush window 14a is curved, that is, at locations where the brush window 14a forms an edge of a three-dimensional plane. This is because the brush base 21 is formed into a flat plate shape at the time of molding, and by attaching it to the mounting frame 14, it becomes an outwardly projecting shape.
This is because the outline shapes of the brush booth 21 and the brush window 14a are difficult to match.

[Means for solving problems]

As shown in the figure, the present invention has a brush window 14a corresponding to the air outlet 6 of the dryer main body 1, a mounting frame 14 attached to the dryer main body 1, and a brush base 21 made of an elastic body with a large number of brittle 22.
A brush 15 is installed, and the peripheral edge of the brush base 21 is supported from inside by the peripheral wall of the brush window 14a of the mounting frame 14 while covering the air outlet 6.
and a brush support 16 that supports the brush 15 from the inner side and keeps it in an outwardly extending shape.
A brush base 21 is installed on the peripheral wall of the brush window 14a.
The brush support 16 is assembled in such a manner that it presses the peripheral edge of the brush support 1 from the inner side.
It is required that a regulating protrusion 33 that bites into the inner surface of the peripheral edge of the brush base 21 protrudes from the brush base 6 .

[Effect]

The peripheral edge of the brush base 21 is connected to the outer mounting frame 14.
and an inner brush support 16. In this assembled and used state, Blitzle 2
When the brush base 21 is tilted, the peripheral edge of the brush base 21 is pulled toward the center and tends to shift at the pinched location. This displacement movement is larger on the outer layer side in the thickness direction than on the inner layer side in the brush base 21 which is maintained in an outwardly extending shape. However, brush support 16
The regulating protrusion 33 protrudes from the brush base 21 and bites into the inner layer portion of the brush base 21. Therefore, the regulating protrusion 33
This can reliably eliminate the problem of the peripheral edge of the brush base 21 shifting.

[Effect of idea]

According to the present invention as described above, the brush base 21 made of elastic material can be securely and firmly fixed. As a result, the brush base 21 can be fixed at a predetermined mounting position in a normal posture and in a state where it is completely fitted to the brush window 14a, and the brush base 21 can be fixed without shifting, especially at the part where the brush window 14a is curved. Can be fixed. Furthermore, when using the hair dryer, the brush base 21 will not shift or turn over due to external force acting on the brittle 22, so there will be no gap between the brush base 21 and the wall on which it is mounted, which will spoil the appearance. It also eliminates losses such as hot air leaking through these gaps.

The dryer main body 1 is made up of front and rear half-split cases 1a, 1b that are butt-joined together, and a motor 3 is supported by upper and lower support walls 7, 7 that protrude from both cases 1a, 1b in a front-back and opposite manner. There is. Further, fan cases 8, 8 surrounding the fan 4 are protruded from both the cases 1a, 1b in a facing manner.

The pressurized air sucked in from the suction port 5 by the fan 4 is heated by the heater 2, and then horizontal and vertical insulating plates 9, 10 arranged in a cross-shaped cross section and a thin metal plate covering the outer surface of these plates are formed. Thermal shield case 11
The air is guided by the air and blows out downward from the air outlet 6.
The air outlet 6 is covered with a grill 13 made of a metal plate, and hot air is blown out from a large number of ventilation holes 13a provided through the grill 13. A brush unit B is attached to the dryer body 1 so as to cover the outer surface of the grill 13.

In FIG. 6, brush unit B includes a boat-shaped mounting frame 14 and a brush window 14 that opens at the bottom surface of the mounting frame 14.
It consists of a brush 15 that is fitted into the brush 15 from above, and a brush support 16 made of a metal plate that holds the brush 15 in a predetermined outwardly projecting shape. Mounting frame 1
4 is formed with an engaging piece 17 consisting of a protrusion in the figure on the inner surface of the front and rear walls, and by guiding and supporting this engaging piece 17 so as to fit into the groove 18 provided on the front and rear edges of the outlet 6, the brush unit can be installed. B is detachably slidably attached from the tip side of the dryer main body 1. Reference numeral 19 is an engagement piece for preventing slippage.

The brush 15 consists of a brush base 21 made of a resilient material such as rubber, and five rows of brittle 22 implanted in the front and rear. The front and rear rows of bristle 22 are each integrally formed into a block shape. That is, the bristle 22 is provided protrudingly provided at a predetermined interval on a bristle base 23 which has a rectangular cross section and is long from side to side. By molding the brush base 21 with this brittle 22 inserted, both 21 and 22 are integrated. Of course, a hole through which the bristle 22 can pass may be formed in advance in the brush base 21, and the bristle 22 may be inserted therethrough. Between the front and back of the wall where the blitzle 22 penetrates the brush base 21,
Oval ventilation holes 24 are provided through the bridging wall at regular pitches.

In FIG. 6, the brush support 16 has the same planar shape as the brush window 14a and is formed to protrude downward, and has a ventilation hole 29 that opens at the same position as the ventilation hole 24 of the brush base 21 on its plate surface. be. In addition, there are mounting frames 14 at two locations on the left and right of the front and rear edges.
A protruding pawl 30 is provided which press-fits into the groove 14b.

The brush 15 and the brush support 16 are sequentially assembled into the mounting frame 14, and the brush base 21 is fixed between the brush support 16 and the peripheral wall of the brush window 14a. The brush base 21, which was flat during molding, is elastically deformed into an outwardly projecting shape only after it is assembled into the mounting frame 14, and the outwardly projecting state is maintained by the brush support 16 on its inner surface.

In this assembled state, in order to prevent the brittle 22 from tilting in the longitudinal and lateral directions, a base holding means 32 is provided on the lower surface side of the brush support 16, as shown in FIG. That is, a bridging wall that separates the ventilation hole 29 of the brush support 16 from side to side projects toward the brush 15 side to form a rib 32a, and this rib 32a
The group constitutes the base holding means 32. The base holding means 32 may be formed by folding the front and rear edges of the ventilation hole 29 downward by burring.
Alternatively, the plate surface may be protruded into a triangular pyramid shape to form a spike shape. The ribs 32a are formed in two rows, front and rear, sandwiching the center row of brittle bases 23 in the front and rear. Note that the rib 32a protrudes from the outer surface of the brush support 16 by about 1 mm.

The present invention is characterized in that the brush 15 is fixed to the mounting frame 14 in the following manner in this hair dryer with a brush.

In FIG. 6, a groove 26 opening downward is formed on the lower surface of the peripheral edge of the brush base 21.
Engagement holes 2 for positioning are provided on the upper wall at appropriate intervals.
7 is installed transparently. On the other hand, the brush window 14 of the mounting frame 14
A projecting wall 28 that fits into the groove 26 is provided along the inner edge of the groove 26, and a positioning piece 28a is provided projecting on the projecting wall 28 in correspondence with the engagement hole 27. In addition, on the side of the brush support 16 that comes into contact with the brush base 21, two
The number of regulating protrusions 33 is formed. This regulation protrusion 33
are provided at two locations, front and rear, corresponding to the proximal end of the curved portion of the brush window 14a, and are formed as annular protrusions by burring.

In the installed state, the brush base 21 is in the groove 26.
The projecting wall 28 and the engagement hole 27 and the engagement piece 28a are positioned by engaging with each other, and displacement in the front, rear, left and right directions is restricted. The brush base 21 is prevented from slipping out and its posture is maintained by the brush support 16, which is fixed by press-fitting the pawl 30 into the groove 14b of the mounting frame 14. In particular, the brush base 21 tends to turn inward at the curved part of the brush window 14a, but since this part is forcibly suppressed by the regulating protrusion 33 of the brush support 16, misalignment at that part and turning of the peripheral wall can be prevented. It can be resolved. As shown in FIG. 1, the regulating protrusion 33 presses the brush base 21 while biting into the flesh wall.
Compared to those that prevent misalignment using only frictional force, a stronger fixing force can be obtained, and the brush base 2
The brush base 21 can be fixed in a state where the brush base 21 is completely fitted into the brush window 14a, and in addition, the brush base 21 can be sufficiently resisted against external forces that cause positional displacement.

In the figure, reference numeral 34 is a switch, 35 is an operation button thereof, and 36 is a suction grill made of punched metal.

[Another example]

8a and 8b show another embodiment of the present invention regarding the regulating protrusion 33. FIG.

In the one shown in FIG. 8a, the regulating protrusion 33 is formed of a cut and raised piece. It is desirable that the cut and raised pieces be cut and raised alternately in opposite directions at small intervals. In this way, the regulating protrusion 33 does not necessarily have to be formed in an annular shape.

FIG. 8b shows a case where the brush support 16 is a plastic molded product, and in this case, the regulating protrusion 33 is formed as a spike-like conical protrusion. In this way, the brush support 16 does not necessarily have to be a metal plate.

In the above embodiment, since the brush unit B is removable from the dryer body 1, the brush 15 and the brush support 16 are respectively incorporated into the mounting frame 14. It may be attached directly to the air outlet 6. In short, it is sufficient that both members 15 and 16 are attached to the peripheral wall connected to the air outlet 6.

Further, in the above embodiment, the regulating protrusions 33 are provided only at particularly necessary locations, but the regulating protrusions 33 may be fixed at 4 to 10 or more locations along the periphery of the brush base 21. .
