Abstract

PURPOSE: To improve safety for handling the edge of a filter made of a punched plate by piercing hales only in the annular area of a metal plate and performing punching along an outer periphery surrounding the annular area and an inner periphery surrounded with the annular area. CONSTITUTION: After a lot of holes 91 are pierced in the annular area A on the metal plate 9, an annular substrate 95 is formed by punching the metal plate 9 at the outer periphery surrounding the annular area A and the inner periphery surrounded with the annular area. This substrate 95 is formed into dome by drawing work. Since the filter produced in this way is cut across the holes, the ruggedness is not caused at the outer peripheral edge or inner peripheral edge to improve safety for handling the edge. Besides, since any other parts or worker is not improved in the case of assembly and further, and the finish of appearance is made satisfactory, the filter can be used also as detachable functional parts.

The filter installed at the inlet of the hair dryer is
Conventionally, hair dryers have mainly been made of synthetic resin with a lattice shape that is integrally formed with the main body housing, but from the viewpoint of strength, the bars that make up the lattice cannot be thin (thin), so the opening ratio has been reduced. It has a low suction resistance, and it is difficult to obtain a highly dustproof filter.For this reason, some metal filters with many holes are used, but conventional metal filters As shown in FIG. 9, a metal plate 9 is provided with a pilot hole 90.
After punching a large number of holes in the hole, a ring-shaped object was extracted along the dashed line in the figure within the area where the holes were provided, and then drawn, as shown in Figure 10. Since the filter body 20 was formed in a dome shape as shown in FIG. For this reason, not only is it difficult in terms of appearance and parts assembly, but also it may damage other parts or cause cuts to the worker during assembly work, and for these reasons, the aperture ratio is Metals have superior advantages over synthetic resins in terms of dust and dust resistance! ! ! The spread of filters is slow.

Therefore, the present invention forms a ring-shaped substrate by punching out a large number of holes in a metal plate in an annular area, and then punching out the metal plate at an outer periphery surrounding the annular area and an inner periphery surrounded by the annular area. Then, this substrate is drawn into a dome shape, and by drilling holes in the area of the annular substrate formed by the punching color, holes are formed at the punching lines. This prevents unevenness from occurring due to crossing the surface. The present invention will be described in detail below based on the illustrated embodiments.
As shown in the figure, when punching holes in the metal plate 9 provided with the pilot holes 90, holes are punched to form a large number of holes 91 only in the annular area A, and then the annular area Punching is performed on the outer periphery surrounding A and the inner periphery surrounded by the annular region A. This punching creates areas on the outer and inner peripheries of the annular area A where no holes 91 are formed, but these areas are made to have a certain width from the viewpoint of post-processing. Further, when punching out the inner circumference, a pair of locking pieces 93 and 93 each having a locking hole 94 are formed. In the figure, 92 indicates an outer circumferential punch line. Then, an annular substrate 9 formed by the above-mentioned punching
5 is drawn to form a dome shape with a flange 96 on the outer periphery as shown in FIG. 3, and further drawn and cut so that the flange 96 is cut off as shown in FIG. At the same time, a filter main body 20 is formed in which the inner peripheral edge including the locking piece 93 is inserted inside. As shown in FIGS. 5 and 6, a cylindrical protective cap 21 is provided on the inner circumference of the filter body 20 with seven hooks 22 that are locked in locking holes 94 in locking pieces 93. By locking the filter 2, the filter 2 shown in FIG. 1 is constructed. The filter 2 formed in this manner has no irregularities caused by cutting across the hole 91 on its outer and inner edges, and especially since the protective cap 21 is attached to the inner circumference, Even if you insert the power cord through this part,
There is no possibility that the power cord will be damaged. It is preferable from the viewpoint of appearance that the holes 91 formed in the annular region A are arranged radially. An example of a hair dryer equipped with the filter 2 is shown.This hair dryer has a cylindrical main body 1 with an inlet 10 at one end and an outlet 11 at the other end, and a switch handle 18 on the outer peripheral surface of the main body 1. .19, and the motor 12 and 7T are installed in the main body 1.
At the end on the side of the outlet 11, two types of steam type heating units 3A and 3B are detachably installed. and,
The filter 2 has its outer periphery fitted to the edge of the suction port 10, which is an opening at one end of the main body 1, and is placed in the suction port 10. Power is supplied from the center of the filter 2 via the rotary connector 4. A code 40 has been derived for . The rotary connector 4 is provided to prevent the cord 40 from twisting in view of the fact that the hair dryer is equipped with curl units (7) 3A, 3B as described above. τEffects of the Invention As described above, in the present invention, the hole is drilled only in the annular region, and the punching is performed in the outer periphery surrounding this annular region and the inner periphery surrounded by the annular region. Filters manufactured using this process do not have irregularities on the outer or inner edges caused by cutting across the pores (this improves safety in handling the edges). It does not cause any damage to other parts or workers when it is assembled, and its good appearance makes it possible to use it as a removable functional part. Since the process is only carried out within the annular area, only minor changes to conventional equipment are required.
