チメント２９取付用の操作釦である。 The present invention will be explained in detail below with reference to Examples. The housing 1 is formed into a substantially cylindrical shape by combining a pair of substantially semicylindrical housing halves 1a and 1b molded from synthetic resin.
A motor block 7, a fan 8 connected to the motor block 7, a heater block 9, etc. are built into the motor block. As shown in FIGS. 1 to 3, a suction port lattice 10 is provided at the rear end opening of the housing 1 and protrudes radially from the inner circumference of the opening edge toward the center, and between each suction port lattice 10, 10. An air suction port 2 is formed. A protrusion 11 is formed at the tip of the suction port lattice 10 at the center of the rear end opening, and the peripheral wall of the protrusion 11 extends from the upper end surface of the protrusion 11 to the peripheral wall as shown in FIGS. 3 and 6. A pair of guide grooves 12 are formed in the circumferential wall at positions facing each other at 180 degrees, and an engagement recess 13 is formed in the vicinity of the guide grooves 12.
A protrusion receiving part 14 formed of an H-shaped rib piece is attached to the lower peripheral wall of the protruding part 11, and a cylindrical fixing ring 15 is fitted into the protruding part 11 to form a fixing part at the lower part of the fixing ring 15. By engaging the projection 16 with the projection insertion opening 17 of the projection receiving portion 14, the pair of housing halves 1a, 1b are firmly fixed. The filter 3 is made of an elastic synthetic resin material, etc., and has a substantially truncated conical shape with the housing 1 side open as shown in FIG. 18 and insertion ribs 4 are formed over the entire circumference, and a filter lattice 19 is provided between both reinforcing ribs 18 and 4 to reinforce the filter 3. Furthermore, a lattice-like net 20 is formed between each of the reinforcing ribs 18 and 4, and this net 20 filters air. A notch 21 cut in a direction perpendicular to the circumferential direction is formed in the filter 3 so that the filter 3 can be freely expanded.
This makes it possible to bend the filter 3 and change the opening width of the notch 21. A pressing protrusion 5 is provided on the outer surface of the insertion rib 4 in the vicinity of the notch 17 of the filter 3 so as to protrude outward.
The cover 22 is formed in a cylindrical shape, and protruding dowels 23, 23 as shown in FIG. 5 are provided on the inner periphery of the lower part of the cover 22 at opposing positions. In the figure, 25 is a main switch, 26 is a heater changeover switch, 27 is a power cord, 29 is an attachment that is detachably attached to the front end of the housing 1, and 28 is an operation button for attaching the attachment 29.

スムーズに行えるものである。 Therefore, when attaching the filter 3 to the air suction port 2 of the housing 1, first fit the fixing ring 15 onto the outer periphery of the protrusion 11 as described above, and then insert the fixing protrusion 16 of the fixing ring 15 into the protrusion receiver. Then, the filter 3 is fitted into the protrusion 11 , and the cover 22 is fitted into the protrusion 11 from the outside of the filter 3 , and the protrusion dowel 23 of the cover 22 is inserted into the protrusion 1 .
Fitted into the guide groove 12 provided on the outer peripheral wall of 1,
Next, by twisting the cover 22 and engaging the protruding dowel 23 with the engagement recess 13, the cover 22 is fixed to the protrusion 17, and the filter 3 is fixed to the fixing ring 1.
5 and the cover 22. At this time, the filter 3 is pushed slightly toward the housing 1, and the insertion rib 4 of the filter 3 is supported by the stopper rib 24 provided on the inner periphery of the rear end of the housing 1, as shown in FIG. It also comes into contact with the inner circumferential surface of the housing 1. Further, the pressing projection 5 protrudes laterally at a rear position of the rear end peripheral wall of the housing 1, and the tip of the pressing projection 5 is connected to an inclined surface 6 formed at the rear end of the housing 1.
It is located between the rear extension line l 1 and the rear extension line l 2 of the outer peripheral wall of the housing 1 . Here, connect the tip of the pressing protrusion 5 to the rear extension line of the outer peripheral wall of the housing 1.
By providing the pressure protrusion 5 on the inside of l 2 , the pressure protrusion 5 does not touch your hand when using the hair dryer, and the pressure protrusion 5 can be sucked into the housing 1 by the filter 3 without any trouble. It is capable of filtering the air that is exposed to the air. on the other hand,
When it is desired to remove the filter 3 from the housing 1, the cover 22 is removed from the protrusion 11, and then the filter 3 is bent. In this case, by providing a pressing protrusion 5 protruding on the outer surface of the insertion rib 4, the pressing protrusion 5 of the filter 3 is pushed inward and the filter 3 is bent by its elasticity. The filter can be removed from the periphery, thereby making it easier to remove the substantially truncated conical filter 3, which has a slippery outer surface. At that time, the tip of the pressing protrusion 5 is connected to the inclined surface 6.
By protruding outward beyond the rear extension line l1 , simply by sliding your hand backward along the inclined surface 6 of the housing 1, your hand will come into contact with the pressing protrusion 5, and the filter 3 can be easily removed. The filter 3 can be removed, and especially by adding an outwardly curved radius to the inclined surface 6, the hand can slide more smoothly and the removal operation of the filter 3 can be performed smoothly.

きるものである。 In the present invention, an air suction port is formed at the rear end opening of the housing, and a freely expandable filter with a notch is formed into a substantially truncated conical shape with an opening on the housing side, and a rib is inserted into the periphery of the filter on the housing side. The hair dryer is provided with a pressing protrusion protruding near the notch for bending the filter, and an insertion rib of the filter is removably fitted to the inner periphery of the air suction port of the housing. , a pressing protrusion is provided on the outer surface of the insertion rib, and an inclined surface is formed at the rear end of the housing that slopes rearward inward from the outer periphery of the housing, and the rear extension line of this inclined surface and the outer periphery of the housing are formed. Since the tip of the pressing protrusion is positioned between the rear extension line and the filter, even though the filter is approximately truncated, the insertion rib can be air-filled with the filter compressed through the notch. It can be easily installed by fitting it into the inner circumference of the suction port, and it can be installed securely without expanding when installed, and the pressing protrusion allows the filter to flex when removed. Moreover, in this case, simply by sliding your hand backward along the slope of the housing, your hand will come into contact with the pressing protrusion, making it even easier to remove the filter. It is something that can be done.
